双[2-(2'-苯氧基)苯并恶唑]二吡啶合锰(II)配合物的研究

X射线晶体结构分析结果表明, 标题化合物晶体(C36H26MnN4O4)属单斜晶系, 空间群为P21/a, a=0.9833(3), b=1.8646(3),c=0.9449(1)nm, Z=2, 最终因子Rw=0.057。利用热重分析对配合物晶体两步热分解过程进行了非等温热力学研究, 探讨了反应的可能机理, 得到其相应的动力学参数。第一步非等温动力学方程为: dα/dt=A.exp(-E/RT).2(1-α)^1^/^2, 第二步: dα/dt=A.exp(-E/RT).3/2(1-α)[-ln(1-α)]^1^/^3。

Synthesis, crystal structure and thermal decomposition of bis[2-(2'-phenoxyl)-benzoxazole]-di-pyridine manganese(II)

The title complex C36H26MnN4O4 was synthesized and its strucutre was determined by single crystal X-ray diffraction method. The crystal is monoclinic system, space group P21/a, a=0.9833(3), b=1.8646(3), c=0.9449(1)nm, Z=2, final Rw=0.057 for 1217 observed reflections [I≥3σ(I)]. The kinetics of thermal decomposition reaction of the title complex was studied under non-isothermal condition by TG. The kinetic parameters were obtained from the analysis of TG, DTG curves by integral and differential methods. The kinetic first step dα/dt=A.exp(-E/RT).2(1-α)^1^/^2; second step : dα /dt=A.exp(-E/RT).3/2(1-α)[-ln(1-α)]^1^/^3.
